BACKGROUND: Inorganic component is made up largely of salt, because the criteria are difficult to split into domestic and imported ingredients, organic examined the fatty acid composition is to see a possible use as a marker using gas chromatography-mass spectrometry (GC-MS). The 14 domestic samples and 8 imported samples were collected from China, India and other countries were investigated on item of 37 fatty acids. METHODS AND RESULTS: The major components were six species, myristic acid (), palmitic acid (), palmitoleic acid (), stearic acid (), oleic acid (), linoleic acid () among detected twenty fatty acids including 9 unknowns. The content of palmitic acid were highest as 25.2 to 50.8% of total fatty acids contents. Domestic has seen the most amount of salt in the Taepyeong salts /100g, imports /100g salt in Chinese Weifang salts showed the lowest content. CONCLUSION(s): The total fatty acid content has seen the most amount of salt in 352.3 ug/100g Christmas island salts showed the lowest content of /100g, as a result it is difficult to distinguish the domestic salts and imported by the composition of fatty acid.
